IPC: B63B29/12
Filed: 1932-09-01
Abstract: 392,036. Self-levelling apparatus. SHEVLIN, J. T., 15, South Street, London. -(Pintsch Akt.-Ges., J.; 71, Andreasstrasse, Berlin.) Sept. 1, 1932, No. 24429. [Class 113 (i).] In self-levelling apparatus in which the object a to be maintained level, for example, a device for emitting or receiving optical, acoustic or electric signals, is gimbalmounted at b and is stabilized by a counterweight c which may be adjusted on the rod a, dumping means are provided in the counterweight comprising the cylinders d, connected at top and bottom by the tubes e, f. The cylinders are partly filled with fluid and when the whole system is oscillating, the lag of the fluid relative to the oscillation of the counterweight tends to bring the system to rest as in the case of anti-roll tanks in ships. The flow of liquid through the connecting-tubes may be controlled by throttle valves. The tubes may be external to the body of the counterweight and may be protected by top and bottom coverplates.

Title: Improvements in systems for automatic frequency-control
IPC: H03L7/22
Filed: 1948-09-23
Abstract: 660,139. Automatic frequency control systems. PHILIPS ELECTRICAL, Ltd. Sept. 23, 1948 [Sept. 26, 1947], No. 24915/48. Class 38 (iv). A tunable frequency-corrected oscillator 6 is maintained at a determined frequency separation from any desired component of a frequency spectrum (e.g. that generated by a pulse source 1) by the use of an auxiliary source 2 brought into agreement with the desired spectrum component by means of a mixer 3, low-pass filter 4, and frequency corrector 5. The main oscillator 6 is then automatically maintained at the determined frequency separation from the source 2 by mixing oscillations from the sources 2, 6 in the mixer 8 and passing the resultant beat to a further mixer 11, fed also from a source 10, the frequency of which is adjustable to the desired frequency separation. The output of the mixer 11 passes through a low-pass filter 12 to a frequency controller 9 associated with the main oscillator. In a modified arrangement, Fig. 1 (not shown), the source 10 and mixer 11 are dispensed with, and the output of the mixer 8 is fed to a discriminator the tuning of which is adjustable to the determined frequency separation. The discriminator output supplies a regulating voltage to the frequency correcting device 9. Manual setting of the tuning of the oscillators 2, 6 may be effected by ganged control, utilizing the known means used in superheterodyne radio receivers for maintaining alignment. The limit frequency of the filter 4 should be about half the frequency interval of successive spectrum components. Specifications 640,351 and 670,877 are referred to.

Title: Systems for detecting the skidding of wheels of railway vehicles
IPC: B60T8/32
Filed: 1959-07-22
Abstract: 882,383. Electric selective signalling systems. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. July 22, 1959 [July 24, 1958], No. 25138/59. Class 40 (1). In a system for detecting skidding in railway vehicle wheels, the frequencies of pulse trains, each proportional to the individual speeds of the wheels, are compared with each other and also with the frequency of a further pulse train representing the absolute speed of the vehicle and produced by a magnetic recording and receiving device co-operating with the track. In a first embodiment, Fig. 1, an oscillator 1 feeds A.C. through modulators 2, 3 controlled by the respective driving wheels, and two-state devices 6, 7 to a frequency comparator 80 which also receives a further signal, at a frequency proportional to the absolute speed of the vehicle, from a magnetic recording and pick-up device 9 ... 11 co-operating with the track 12. This device may be of the type described in Specification 818,782. A head 9 records a magnetic signal on the rail which is subsequently picked up by a head 10; when a further head 11  picks up the signal it causes the head 9 to record a new signal, and so on. The device is not effective when the vehicle is travelling slowly. The modulators 2, 3 may each comprise a stationary cored inductor the impedance of which is varied by teeth or like projections moving with each driving wheel (Figs. 2 and 3, not shown). In another embodiment counters are used instead of a frequency comparator. Four wheelcontrolled modulators 2 ... 5, Fig. 4, supply, via two-state devices 6 ... 9, counters 15 ... 18, each of which can count to 31 before returning to zero; they are also zeroized by signals appearing on line 19 or line 20. If any counter reaches 29, say, before a zeroizing pulse arrives, and the other counters have not reached this state, a signal is sent to the appropriate one of four alarm relays al . . . a4 to indicate by means 21 ... 24 that a wheel is skidding and initiate corrective action. If all the counters reach 29 together an interconnecting arrangement 30 blocks operation of all the alarm relays al ... a4. A further four alarm relays bl . . . b4 are made receptive when the device 10 picks up a signal laid down by head 9 (only operative above a certain speed) and are subsequently blocked when the device 11 picks up the signal. During this interval if any of the counters reaches a count of 27, say, the corresponding alarm is operated.

Filed: 1926-10-12
Abstract: 280,014. Cooch, H. Oct. 12, 1926. Counters actuated by electric and magnetic means. - The movements to be counted cause alternate excitation of two electromagnets the common armature of which controls an escapement mechanism, the arrangement being such that the escape wheel receives impulses from the ratchet pawls to supplement the action of its spring. The escapement mechanism consists of a ratchet wheel 6 geared with the index hand 7 and engaged by linked pawls 5 one of which is pin-and-slot connected to an armature 3 pivoted at 4. The electromagnets 1, 2 are in circuit with contacts 24, 25 alternately engaged by a switch arm 17 reciprocated by the moving part. The index hand tends to turn clockwise under the action of a spiral spring 13, and when the armature oscillates the pawls act to release, impel, and hold the ratchet wheel. The apparatus may be applied to machine guns for counting the rounds remaining in the magazine, the switch arm 17 being actuated by the recoil. The construction permits of the hand being set back to any desired number and this may be effected by an external handle adapted to be put in gear with one of the wheels of the reducing train, 10, 11.
